“…Previous study showed preoperative 3D planning technology improved the accuracy of implant position in primary THA [10]. However, application of 3D simulation and model to assist TM cup and augments positioning in revision THA was rarely reported [11, 12]. We aimed to evaluate the advantages and disadvantages of this technology and to provide suggestions for its clinical application in revision THA with complex acetabular defect.…”

BackgroundRevision total hip arthroplasty (THA) with large acetabular defect remains a challenge. Though trabecular metal (TM) cup and augments have been introduced in defect reconstruction with good result, the accurate positioning of implant is important to avoid complications. Therefore, we aimed to evaluate the usefulness of three-dimensional (3D) simulation and 3D model in assisting implant positioning during complex revision THA.MethodsSixteen patients (18 hips) who underwent revision THA with a Paprosky type III acetabular defect were analyzed retrospectively. Placement of acetabular cup and TM augments was simulated with 3D simulation software and 3D model preoperatively. Cup anteversion, abduction angle, and hip center were measured in each case preoperatively and postoperatively. Primary outcome was the percentage of outliers according to Lewinnek safe zone and Harris hip score (HHS). Secondary outcome was the correlation between the 3D planned and the postoperative value.ResultsThe percentage of outliers was significantly corrected from 77.78% (14/18) preoperatively to 38.88% (7/18) postoperatively (p = 0.04). There was a significant correlation between mean planned cup anteversion and postoperative value (13.39 vs 11.99, r = 0.894; p < 0.001). There was a significant correlation between mean planned abduction and postoperative value (42.67 vs 44.91, r = 0.921, p < 0.001). The number of planned and used augments was the same in all the cases. In 15 cases (83.33%), the size of planned and used TM augments was the same. The HHS was significantly improved at final follow-up (80.94 vs 27.50, p < 0.001). No cases presented dislocation or radiological signs of loosening.ConclusionPreoperative 3D simulation and model were considered the useful method to assist implant positioning in revision THA with complex acetabular defect, with moderate to high accuracy and satisfied clinical outcome.

“…Marongiu et al 14 proposed a 3D printed model to help evaluate the fracture pattern and plan for fixation, this has also been proposed in difficult revision arthroplasty scenarios. 15 However, there are cost and time implications with these techniques and they may not be readily available in all centres.…”

Introduction: and aim: Traumatic peri-prosthetic fractures are relatively rare fractures that pose a significant surgical challenge. They have a fracture pattern that is different from its iatrogenic counterpart. This study aimed at reviewing the modalities of treatment of such injuries, proposing a treatment algorithm and reporting the outcomes of these injuries. Patients and methods: We propose an algorithm for management of traumatic peri-prosthetic acetabular fractures which depends on fracture displacement, implant stability and associated bone loss. Twelve patients with traumatic peri-prosthetic acetabular fractures were treated between January 2012 and December 2018. All patients were treated surgically. Patients were allowed immediate weight bearing as pain allowed. Assessment was carried out using the Oxford Hip Score (OHS) and the Merle D'aubign e score (MDP). Results: Mean patient age 71 (range: 59e80). 8 patients underwent implant removal, fracture fixation and re-implantation of revision acetabular cup (displaced fracture, unstable implant, adequate bone stock). Three patients required acetabular reconstruction (inadequate bone stock). One patient underwent revision acetabular component. One patient suffered from recurrent dislocation that required surgical intervention. Mean follow up was 27 Months (range 12e48). Mean OHS was 36 (range 10e47). Mean MDP was 12 (range 9e18) with 80% excellent and good results. Conclusion: Surgical management of peri-prosthetic acetabular fractures can produce good to excellent results provided adequate assessment and surgical planning have been carried out. Fracture displacement, implant stability and bone stock should be carefully assessed.

printing technology has revolutionized how the authors examine, diagnose, and treat various medical conditions across a wide range of specialties. Synonymous with additive manufacturing, 3D printing fuses materials together layer by layer in 2-dimensional crosssections to build the finished 3D product. This technology has proven superior to other manufacturing methods in certain instances because of its flexibility in the design process to create personalized products on demand. Within the field of orthopedics, 3D printing's popularity has been driven in part by its capacity to address difficult cases in which the design must meet unique anatomic or pathologic criteria. As its use has become more common, so have the ways in which the field has adapted 3D printing technology to improve patient care. This review outlines the basics of 3D printing technology and its current applications in orthopedics: anatomic models, noncustom implants, patient-specific instrumentation, and patient-specific implants. The authors then briefly summarize 3D bioprinting and how it could impact bone and cartilage restoration in the future.
